Methodology: Retail & Restaurant Operating Metrics
What these figures are
The Operating Metrics card on a retailer’s or restaurant company’s stock page shows the operating statistics the company reports in its own quarterly earnings release — the SEC Form 8-K exhibit filed alongside the results. These are the numbers used to describe how the existing store or restaurant base is performing, how many people are visiting, how much they spend, and how large the system is. Oxford Ledge reads them directly from the as-filed exhibit and normalizes the labels so you can compare a company to itself over time.
They are an Oxford Ledge Signal: our reading of a public filing, not a re-audit of the company’s books and not a licensed data-vendor feed. Every value on the card carries its filing as-of date and links back to the SEC source.
The metrics, in plain English
| Metric | What it measures |
|---|---|
| Comparable sales | The change in sales at locations open at least a year (“comps”) — the core-demand measure, separating existing-store performance from new openings. |
| Traffic & average ticket | The change in the number of transactions, and the change in average spend per transaction — the two halves of a comp. |
| Systemwide sales | Total sales across all locations including franchisees — the truer measure of a franchised brand’s scale than the parent’s own reported revenue. |
| Unit count | The number of stores or restaurants — the scale of the system and, with net new units, a growth lever on top of comps. |
Why the peer table separates retail from restaurants
A restaurant comp and a retailer comp answer different questions and move on different dynamics — a restaurant lives on traffic and menu pricing, a retailer on foot traffic and basket size, and their comp conventions differ. Pooling them into one ranking would mislead. So the peer table is split by subcohort (Restaurants, Retail), and you pick one. Each subcohort is its own comparable series; a blank cell inside a subcohort is an honest coverage gap, never a value pooled in from the other type.
Why comparable sales shows a definition
“Comparable sales” is not defined identically by everyone. A franchised restaurant brand reports systemwide comps (all locations, franchised included) as its headline; a retailer reports a company-operated / reported comp; a convenience-store operator reports an ex-fuel comp so that volatile fuel prices don’t swamp the merchandise trend. These are different measures. We treat the headline systemwide/reported comp as the figure to compare, and badge a company-operated or ex-fuel comp so a reader knows which one they are looking at; on the peer table, the comp column pins the headline definition.
How we read and normalize it
For each company we fetch the most recent quarterly earnings 8-K exhibit from SEC EDGAR, locate the operating table, and read each value verbatim from the reported column — never a prior-year or year-to-date column standing in for the quarter. We bind the subcohort (retail vs restaurant) and record each comp’s definition (systemwide, reported, company-operated, ex-fuel) alongside it, and read traffic and ticket as their own independent figures.
The reading is checked against a hand-verified golden set for each company before any figure is allowed to publish; a value whose definition the extractor cannot confidently determine is withheld rather than shown.
What we deliberately do not do
- We do not re-audit. The figures are as reported by the issuer under regulatory convention. We normalize labels; we do not restate the company’s numbers.
- We do not pool retail with restaurants. The two subcohorts are separate comparable series.
- We do not re-normalize a comp definition. Each comp is read as reported; the peer table compares the headline definition and leaves the rest blank.
- We do not treat these as forecasts, ratings, or advice. They are historical operating results a company disclosed, presented for study.
Freshness
The stock page is cached at the edge, so a brand-new filing’s figures can lag up to a day on the cached page. Each value is stamped with the filing it came from, so the as-of date always tells you exactly how current the number is.
